Hehe... I started looking at this, and found that I can use xev in a KDE terminal to see the button presses...What I noticed is that all the keys that the FiireChief uses are the same as the Dinovo Mini for Play, Stop, Pause, Vol+-, Record...

I'm running 8.10 Alpha and the Dinovo buttons does not work, but neither does the Fiire Chief...So for fun I booted 7.10 (I'm using dual boot) and fired up a video, and YES the Dinovo Mini just works!

I can pause, skip and stop. The volume goes up and down...

So I guess editing the options file is the only thing needed to get this baby working

The strange thing is that the MCE button does not pass a button press. And I would really like to map the F7 function to the MCE button.
